The conflict was pretty basic and I think was way too short considering what it was about. It just kind of pops up and disappears within a max of three pages. The mpreg also kinda gets sprung on at the end of the story but Hayley was so cute and I liked the way Zack and Simon's relationship evolved. Especially since Simon was forced to accept both Hayley and Zack and not just Zack. Plus, Zack is a ginger and that's like a major kink for me.
Overall, a nice story I really liked especially since the mpreg was added into it. ^_^
